Rule 1 governs the procedure in which courts?

• A. All state courts
• B. Any federal court
• C. Supreme Court only
• D. United States district courts

Answer: (D)

Rule 1 defines the scope of the Federal Rules of Civil Procedure: they govern the procedure in the United States district courts. These rules set how civil actions are brought, managed, and decided in federal trial courts, aiming for just, speedy, and inexpensive outcomes. They do not apply to state courts, which use state procedural rules, nor to the Supreme Court or federal appellate courts, which follow their own separate rules (like the Federal Rules of Appellate Procedure). So the best answer is United States district courts.
